HOT-WATER EURNACIL 1 Application filed August a1, 1927. Serial in.216,865.

This invention relates to new anduseful improvements in furnaces andaims to provide a furnace that is constructed for producing hot air andhot water.

5 In carryin out the present invention the device inclu es generally afurnace casing within which is a fire box for heating the air within thecasing from whence the same is led to the floor of the building directlyabove the furnace floor, the structure further including a 'hot waterheating chamber that surrounds the fire box and from which the water isled to conventional radiators within the up er floors. Obviously, abuilding may 16 be uni ormly heated at low cost. Furthermore, thepresent furnace may be manufactured and marketedat a cost no greaterthan the ordinary hot air or hot water furnaces now generally in use.

20 In the drawings wherein like reference characters indicatecorresponding parts throughout the several views:

Figure 1 is a fragmentary vertical section through a bliilding withinwhich is arranged a heating plant that includes a furnace constructed inaccordance with the present invention, the same being in detail verticalsection. a

Figure 2 a detail enlarged horizontal section through the furnace takensubstantially upon the line 2-2 of Figure 1.

Figure 3 is a fragmentary view partially in inner perspective and invertical cross section of the water chamber of the furnace,

85 and Figure 4 is a detail fragmentary section thereth-rough.

Now having particular reference to the drawings my improved furnaceconsists of 40 a conventional shell or casing 5 within-which is arrangeda fire chamber 6 having spaced 7 relation with the shell or casing andequipped at its lower end with a conventional fire ,grate 7. The shellor casing 5 is equipped at its upper end with a plurality of hot airdischarge pipes 8, while the upper end of the fire chamber 6 isconstructed with an shell or casing 5 and at its upper end with the roomof the building directly above the room within which is disposed thefurnace so that the cold air passes through the casing adjacent thefloor. The fire chamber is formed atits lower end with an ash pit havingan air inlet opening, and clean out 10.

In front of this opening the shell or casing is provided with a cleanout opening that is normally closed by a suitable door 11. Forming theannular wall of the fire chamber-6 directly above the grate 7 is a waterreceiving unit 12. This unit consists of a circular metallic shell 14formed or constructed at its upper and lower ends with circular watermanifolds 1515. These manifolds are in communication with each other byreason of vertically extending tubes 16, while leading into the lowermanifold is a cold water pipe'17 that has communication with a source ofsupply as suggested in Figure 1. The shell 14 of this water unit isformed with a forwardly projecting mouth 18 that affords an opening intothe fire chamber 6 therethrough, this month being in registration withan opening in the shell or casing 5 over which is a normally closed door19.

In actual practice conventional water ra"- diators 20 are arranged inthe upper floors of the building, and thathave communication at certainends with the upper manifold 15 of the water unit by reason of pipes2121. The pipe 21' is bent over the top of unit through the radiatorsand thence returned into the lower manifold as clearly disclosed inthediagrammatic view in Figure 1.

In view of the foregoing'description when considered in conjunction withthe accompanying drawings it will at once be apparent that I haveprovided a highly novel, simple, and extremely useful hot air and hotwater heating furnace that is well adapted for all the purposesheretofore designated, even though I have herein shown and described theinvention as consisting of certain detailstructural elements, it isnevertheless to be understood that minor changesmay be made 5 thereinwithout affecting the spirit and scope of the appended claim.

. Having thus described the invention, What I claim as new is v In afurnace of'the character described, 8.

fire box formed with a circular wall, a water 10 manifold at the upperand lower ends of the:

wall, tubes formed on the inner surface of the wall and connecting themanifolds, an

outlet pipe for the upper manifold, and an inlet pipe for the lowermanifold. 15

r In testimony whereof I aifix my signature.

CHARLES 'J. STRICKER.
